Abstract:
In this study, an EHCO PLUS- 2ZZ-GE-02 model light vehicle was used to analyze the fuel performance with the 
consideration of the effect of wheel alignment and shock absorber conditions. In the experimental setup, a computerized 
machine vision-based wheel alignment measuring system was used to detect the misalignment of the wheels and the fuel 
performance of the vehicle measured before and after wheel alignment. The analysis results reveal that fuel consumption 
depends on wheel alignment. Also, the wheel alignment has been greatly affected by shock absorber conditions. Through 
the experimental process, it is found that wheel misalignment under inflation pressure in the tire and improper shock 
absorber condition resulted in increasing the fuel consumption rate. However, the fuel consumption rate of the vehicle has 
significantly improved by adjusting the alignment of wheels.
